[Solved] Content Encoding Error

Hellow i just install Open Cart on my server, my Admin page it works but Store Front dont work i get this error:

"Content Encoding Error

The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression.

* Please contact the website owners to inform them of this problem."

And in error log i get error like this:
"2010-02-02 16:27:13 - PHP Warning: imagejpeg() [<a href='function.imagejpeg'>function.imagejpeg</a>]: Unable to open '/var/www/kartel/image/cache/data/ipod_classic_1-120x120.jpg' for writing in /var/www/kartel/system/library/image.php on line 43"

i verify the image.php at line 43 and there is this line: "imagejpeg($this->image, $file, $quality);"

why do i get this error?

This error is usually caused from the Compression/Encoding. Try reducing the level set in: Admin -> System -> Settings

Output Compression Level:
GZIP for more efficient transfer to requesting clients. Compression level must be between 0 - 9
